Serial No. 852,955.

The operation of my inventionwill be readily understood and is asfollows: The

spring is usted to the pressure upon the water in the supply pipe, saidvalve being normally open when the tank is empty. As the water raisesthe float, the valve will move to its seat and autonmtically shut offthe supply.
